CROSS-REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Application 202122056689.8, filed Aug. 27, 2022, and titled “Cleaning Device And A Dust Box Assembly Thereof,” and incorporates the entire content of the prior application by this reference.

BACKGROUND

The present application relates to the technical field of cleaning technology, and in particular to a cleaning device and dust box assembly. With the development of intelligent manufacturing technology as well as communication technology, more and more smart home devices are serving people and bringing great convenience.

Automatic cleaning devices, such as sweeping robots and vacuuming robots, can automatically or semi-automatically perform cleaning tasks such as floor cleaning and dusting, and the absorbed waste are retained in the cleaning device. There are two methods to remove the waste from the cleaning equipment: manually cleaning the garbage left in the cleaning equipment, or automatically cleaning the garbage left in the cleaning equipment using a base station. In the second method, the base station and cleaning equipment has become a more widely used cleaning system, but the current cleaning equipment is less efficient in pumping (e.g., pushing) the waste inside it through the base station, and the degree of cleaning is low, resulting in a large number of waste objects still left inside it without being effectively pumped.

SUMMARY

The main technical problem solved by this application is to provide a cleaning system (e.g., a cleaning device) and its dust box assembly, which can improve the cleaning efficiency of the waste inside the cleaning system.

To solve the above technical problems, one of the technical solutions used in this application is to provide a cleaning system (e.g., a cleaning device). The cleaning system may comprise a cleaning apparatus connected to a base station, a suction channel formed between the base station and the cleaning apparatus; and a switching assembly provided in the cleaning apparatus. The waste (e.g., dirt) in the cleaning apparatus may be suctioned through the suction channel. The switching assembly may be configured to intermittently block (e.g., seal, close) the suction channel to change the pressure of the cleaning apparatus (e.g., when the waste in the cleaning apparatus are being suctioned out). The switching assembly may be configured to intermittently block the suction channel in response to the cleaning apparatus being coupled to the base station (e.g., return to the base station after cleaning). The cleaning apparatus may be removably couplable to the base station and comprising a self-propulsion system.

In order to solve the above technical problems, another technical solution adopted in this application is to provide a dust box assembly, which may comprise a dust box and a switching assembly. The dust box may be used to connect to a main body of the cleaning apparatus to form an airflow path within the main body. The switching assembly may be provided in the dust box for intermittently blocking the airflow passage so that the pressure in the airflow passage changes intermittently as the waste in the dust box are being vacuumed.

The suction channel formed between the cleaning apparatus and the main body of the base station may be intermittently blocked by the switching assembly, so that intermittent suction or similar pulsed suction can be realized when the base station suctions the waste in the cleaning apparatus through the suction channel. The pressure of a holding cavity may change during the switching process, which leads to an instantaneous increase in airflow velocity, so that the waste attached to the cleaning apparatus could be loosened and then suctioned. The cleaning system described in the current application has a stronger suction power and better suction effect. Additional advantages and features of the present application will be described in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF EMBODIMENTS

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the present application. The described embodiments are only a part of the embodiments of the present application, and not all of them. Different embodiments of the present application may be combined in part or in whole. Based on the embodiments of this application described in this application, all other embodiments obtained by a person skilled in the art without creative labor shall fall within the scope of protection of this application.

As shown in FIG. 1 , a cleaning system 1 described in this application may comprise: a cleaning apparatus 100 (e.g., a cleaning device) and a base station 300. The cleaning apparatus 100 may be used to pick up and store waste. The cleaning apparatus 100 may be, for example, a cleaning robot or vacuum cleaner, etc., with cleaning functions such as sweeping and mopping the floor. The cleaning apparatus 100 may be a self-propelled cleaning device, capable of walking autonomously and/or under command control, and thus carrying out cleaning tasks.

The base station 300 may be connected to the cleaning apparatus 100 for vacuuming the waste stored in the cleaning apparatus 100 and may be referred to as a dust collection base station. In this way, it is possible to remove the waste inside the cleaning apparatus 100 without manual work. The base station 300 may be capable of charging the cleaning apparatus 100. The cleaning apparatus 100 may automatically move to the base station 300, and may start charging after connecting to the base station 300. The base station 300 may also clean the cleaning apparatus 100, such as cleaning the side sweep and/or mopping mechanism on the cleaning apparatus 100. The base station 300 may further clean the cleaning apparatus 100 after pumping the cleaning apparatus 100 to eliminate the need for manual cleaning of the cleaning apparatus 100. The functions of the base station 300 can be many, and the above list is only an example. The cleaning system 1 has many functions, and the following functions and structures are only exemplary illustrations of one or more of them.

Function 1: The cleaning system 1 can realize intermittent suction or similar pulsed suction, making the suction process produce pressure changes. Such pressure changes may increase the instantaneous flow velocity of airflow, and then increase the kinetic energy, so that the waste attached to and/or stored in the cleaning apparatus 100 may be loosened. The cleaning system 1 has a stronger suction power and a better suction effect.

As shown in FIG. 2 and FIG. 3 , the cleaning system 1 may comprise a switching assembly 500 for intermittent pumping of the cleaning apparatus 100 by the base station 300. A suction channel 400 (e.g., a dust communication channel) is formed between the base station 300 and the cleaning apparatus 100, and the waste objects in the cleaning apparatus 100 are suctioned through the suction channel 400. The switching assembly 500 is configured to intermittently seal (e.g., close, block) the suction channel 400 so that the pressure in the suction channel 400 varies intermittently.

The switching assembly 500 can be provided in the base station 300, the cleaning apparatus 100, or both the base station 300 and the cleaning apparatus 100. As shown in FIG. 2 , the switching assembly 500 is provided in the base station 300, and as shown in FIG. 3 , the switching assembly 500 is located in the cleaning apparatus 100. The switching assembly 500 may also be provided outside of the base station 300 and the cleaning apparatus 100, such as being located near the base station 300. The switching assembly 500 may comprise a drive member 510 and a blocking member 520. The drive member 510 is connected to the blocking member 520 for driving the blocking member 520 in an intermittent motion such that the blocking member 520 intermittently seals the suction channel 400.

The base station 300 has a first airflow channel 401, the cleaning apparatus 100 has a second airflow channel 402, and the first airflow channel 401 and the second airflow channel 402 are connected to form the suction channel 400. The switching assembly 500 is used to intermittently seal the first airflow channel 401 and/or the second airflow channel 402. In this embodiment, the switching assembly 500 may be fully blocked or partially blocked when blocking the airflow channel(s), as long as it produces intermittent changes in pressure within the second airflow channel 402. The pressure in the second airflow channel 402 may produce intermittent changes, and the pressure in the first airflow passage 401 may also produce intermittent changes. For exemplary Function 1, this embodiment provides a variety of implementations, as further described below.

First implementation: The switching assembly 500 is provided at the base station 300 for intermittently blocking the second airflow channel 402.

Second implementation: The switching assembly 500 is provided at the base station 300 for intermittently blocking the first airflow channel 401. The first implementation and the second implementation described above may provide a dust collection device that comprises a base station 300 and the switching assembly 500.

Third implementation: The switching assembly 500 is provided at the cleaning apparatus 100 for intermittently blocking the second airflow channel 402. The third embodiment provides a cleaning device that may comprise the cleaning apparatus 100 and the switching assembly 500.

Function 2: The cleaning system described in this embodiment enables the base station 300 to clean the mopping member 134 of the cleaning apparatus 100.

As shown in FIG. 5 , the cleaning apparatus 100 described in the present application may comprise a main body 10 and a dust box 20 attached to the main body 10.

The dust box 20 is installed in the main body 10 by, for example, inserting, assembling the dust box 20 in the main body 10, or combining the dust box 20 with the main body 10. The dust box 20 is used to store dust, debris and other trash. The main body 10 may have various cleaning function such as sweeping and/or vacuuming.

As shown in FIG. 5 , the main body 10 may comprise a body section 11, a walking assembly 12, a sweeping assembly 13, a vacuum assembly 14, a battery assembly 15, a sensing assembly 16, and a control circuit 17. The body section 11 serves as the overall structural framework of the main body 10, including the outer and inner shells, etc. The body section 11 is used to accommodate a plurality of functional parts, electrical devices, and other components to protect the internal components and structure of the cleaning apparatus 100. The body section 11 has a bottom 111, a top 112, and a perimeter 113.

The walking assembly 12 is provided primarily in the body section 11 to make the cleaning apparatus 100 movable. The sweeping assembly 13 is provided in the body section 11 for cleaning (e.g., sweeping) the working surface of the cleaning apparatus 100 (e.g., a floor). The dust suction assembly 14 is provided in the body section 11 for sucking dust, debris and other waste objects into the dust box 20. The battery module 15 stores electrical energy to power components such as the walking assembly 12, the sweeping assembly 13, the vacuuming assembly 14, the sensing assembly 16, and/or the control circuit 17. The sensing component 16 is used to implement one or more corresponding functions, such as infrared function, collision sensing function, etc., for obstacle avoidance, navigation, recharging, etc. The control circuit 17 is coupled to the travel assembly 12, the sweeping assembly 13, the vacuum assembly 14, the battery assembly 15, and/or the sensing assembly 16, respectively, for controlling the above components to achieve the corresponding operations. The control circuit 17 can be an MCU or a circuit board including an MCU that serves as a processing hub for the cleaning apparatus 100.

The travel assembly 12 may comprise a drive mechanism 121 and a rolling wheel mechanism 122. The drive mechanism 121 may be used to drive the rolling wheel mechanism 122 to rotate and travel on the work surface of the cleaning apparatus 100. The drive mechanism 121 may be a motor. The rolling wheel mechanism 122 may comprise two first rotating wheels 1221 and one second rotating wheel 1222. As shown in FIG. 5 , two first rotating wheels 1221 are spaced apart at the bottom 111 of the body section 11. The two first rotating wheels 1221 can be coaxially connected to act as the main drive wheels. For example, the drive mechanism 121 can directly drive the two first rotation wheels 1221 to rotate. As shown in FIG. 5 , the second rotating wheel 1222 is provided at the bottom 111 of the dust box 20 as the drive wheel. For example, when at least one of the first rotating wheels 1221 is driven and then travels, the second rotating wheel 1222 is pushed and travels. The control circuit 17 can control the drive mechanism 121 to perform various functions, such as speed control, steering control, forward-backward control, etc.

The sweeping assembly 13 may comprise a side sweep 131 and a side sweep motor 132. The side sweep 131 is provided at the bottom 111 of the body section 11, and the side sweep motor 132 is used to drive the rotation of the side sweep 131. The side sweep 131 comes into contact with the working surface of the cleaning apparatus 100 and sweeps the floor by rotation. The position relationship between side sweep motor 132 and side sweep 131 shown in FIG. 5 is only schematic, and does not constitute a limitation on the structure, position, connection, transmission, mode of operation, etc. between the two. The drive mechanism 121 of the walking assembly 12 and the side sweep motor 132 of the sweeping assembly 13 may be the same drive component, e.g., both share the same drive system. The control circuit 17 can also control the side scan motor 132 for operation, such as speed control, frequency control, steering control, etc.

As shown in FIG. 5 , the body section 11 is provided with a vacuum port 114, a connection port 115, and an exhaust port 116. The vacuum port 114 and the connection port 115 are connected. After the main body 10 and the dust box 20 are connected, the connection port 115 is connected to the inside of the dust box 20. The vacuum port 114 can also be connected to the inside of the dust box 20. The vacuum port 114 may be opened on the bottom 111 of the main body 10, set toward the working surface of the cleaning apparatus 100 to suck up dust or trash from the working surface.

As shown in FIGS. 6 and 7 , the circumferential side 113 of the body section 11 is partially enclosed to form a holding area 1130 that conforms to the shape of the dust box 20. The holding area 1130 is used to hold the dust box 20 so that the dust box 20 can be assembled with the main body 10. The connection port 115 is opened on the circumferential side 113 and is oriented towards the accommodation area 1130. The exhaust port 116 is opened on the circumferential side 113 and is spaced from the connection port 115. The holding area 1130 may be provided in a generally U-shaped configuration, and the connection port 115 may be opened at the bottom of the U-shaped of the holding area 1130, e.g., the circumferential side 113 faces the middle of the holding area 1130. The exhaust port 116 is opened on both sides of the U-shape of the housing area 1130, e.g., the perimeter 113 is positioned towards both sides of the housing area 1130. The main body 10 has a body channel. For example, the passage formed by the vacuum port 114, the connection port 115 and the exhaust port 116 can be the main passage. The main channel can be a continuous channel or a non-continuous channel.

The sweeping assembly 13 may comprise a roller brush 133, which contacts the work surface of the cleaning apparatus 100 in a rolling manner, and thereby rolls up trash objects such as hair and paper debris from the work surface. The roller brush 133 is rotatably provided in the vacuum port 114 to simultaneously curl and absorb the waste objects during the process of dust suction via the vacuum port 114 to improve the cleaning efficiency.

As shown in FIG. 5 , the vacuuming assembly may comprise a fan 141. The fan 141 is provided adjacent to the exhaust port 116 to form an airflow that passes through the vacuum port 114, the connection port 115, the dust box 20, and the exhaust port 116 in sequence, so that the vacuum port 114 has suction power to suck up dust or garbage from the work surface. The number of fans 141 and the number of exhaust ports 116 may be the same. For example, if the number of exhaust ports 116 is two, then the number of fans 141 can be two. The dust extraction assembly 14 may comprise filter components such as a screen, set between the exhaust port 116 and the dust box 20, allowing larger trash or particles to remain in the dust box 20. The control circuit 17 controls the fan 141 for operation, such as speed control, hour control, etc.

The vacuum port 114 may also be opened on the circumferential side 113 of the main body 10. The holding area 1130 is used to hold the dust box 20, which is used to collect objects such as garbage. After objects such as trash are retained in the dust box 20, the airflow exits through the exhaust port 116.

The sweeping assembly 13 and the vacuuming assembly 14 work in conjunction with each other. The vacuum port 114 is set adjacent to the side sweep 131 so that the trash or dust swept out during the rotation of the side sweep 131 is sucked into the dust box 20.

The battery assembly 15 is used to power the entire cleaning apparatus 100. The battery assembly 15 may comprise a battery 151 and a charging terminal 152, which is electrically connected to the battery 151. The charging cradle charges the battery 151 through the charging terminal 152. The charging terminal 152 is provided on the bottom 111 of the body section 11, exposed on the surface of the bottom 111 of the body section 11, and thus accessible.

The sensing assembly 16 is used to transmit and receive corresponding signals to communicate and interact with other devices around the cleaning apparatus 100. The sensing assembly 16 may comprise at least one infrared sensor, and the infrared sensor may transmit and receive a corresponding infrared signal (e.g., infrared light), and decode the infrared signal to obtain the information, instructions, etc. carried by or corresponding to the signal for obstacle avoidance, communication with the rechargeable seat, etc. The sensing assembly 16 may also comprise one or more of collision sensors, distance sensors, and/or image sensors, etc. The sensing assembly 16 may receive an infrared signal sent by the rechargeable seat, causing the cleaning apparatus 100 to perform an operation corresponding to that infrared signal. For example, the control circuit 17 may decode the infrared signals to obtain the corresponding information or instructions, and then control the walking assembly 12 to work according to the corresponding information or instructions, causing the cleaning apparatus 100 to move to the charging stand for charging.

As shown in FIGS. 6 and 7 , the cleaning apparatus 100 is further provided with a mopping mechanism, such as a mopping member 134. The mopping member 134 is provided in the main body 10 for cleaning the working surface of the cleaning apparatus 100. For example, the mopping member 134 is provided at the bottom 111 of the body section 11. In some implementations, the mopping member 134 can replace the side sweep 131, and the side sweep motor 132 drives the mopping member 134 to rotate and mop the corresponding area. The mopping member 134 may be circular or circular-like. In other examples, the mopping member 134 is provided in other areas of the bottom 111 of the body section 11, spaced apart from the first rotating wheel 1221, the side sweep 131, the roller brush 133, etc. The mopping member 134 may assume a shape that is compatible with other areas or structures. When the cleaning apparatus 100 is in the process of cleaning the working surface, the mopping member 134 is able to touch the working surface to wipe the working surface. The mopping member 134 can be mop, wet wipes or sponge, etc. The above structure of the main body 10 is only an exemplary illustration and is not limited to the above exemplary structure.

As shown in FIGS. 8 to 10 , the dust box 20 is formed with a holding cavity 210 and an air outlet 211 and dust inlet 212 connected to the holding cavity 210. The dust box 20 is also provided with a dust outlet 213 connected to the holding cavity 210.

When the dust box 20 and the main body 10 are connected, the connection port 115 is connected to the holding cavity 210 and the air outlet 211 can be connected to the air exhaust port 116. During the normal operation of the fan 141, airflow passes through the vacuum port 114, the connection port 115, the holding cavity 210, the air outlet 211, and the exhaust port 116 in that order or in a different order. The dust inlet port 212 can be docked with the connection port 115 to allow the air flow drawn in by the vacuum port 114 to enter the holding cavity 210 through the connection port 115 and the dust inlet port 212. The dust inlet 212 and air outlet 211 can be located on different sides of the dust box 20. The number of air outlets 211 may be at least two, with at least two air outlets 211 spaced apart from each other. The dust outlet 213 is used to connect to the base station 300. When the cleaning apparatus 100 is held on the base 320, the dust outlet 213 can be docked and connected to the suction inlet 301 so that the base station 300 can suction the waste objects in the holding cavity 210 via the dust outlet 213. For example, the dust box 20 may form a dust box channel that is connected to the main body channel. The passage formed between each of the dust inlet port 212 and air outlet 211 and the dust outlet port 213 can be the dust box passage. The main body channel and dust box channel are interconnected to form the second airflow channel 402. In this way, at least one of the vacuum port 114 and the exhaust port 116 can serve as the inlet of the second airflow channel 402, e.g., the airflow inlet, during the process of suction. During suction, one of the vacuum port 114 and the exhaust port 116 can be blocked, while the other is used as the inlet of the second airflow channel 402. The dust outlet 213 can serve as the exit of the second airflow channel 402, e.g., the airflow outlet.

In some embodiments, the dust box 20 may be provided without the dust outlet 213. When the base station 300 is pumping the trash objects inside the cleaning apparatus 100, the vacuum port 114 can serve as the outlet of the second airflow channel 402, and the trash objects inside the holding cavity 210 flow out from the vacuum port 114 to the base station 300 with the airflow, while the exhaust port 116 serves as the inlet of the second airflow channel 402. In this way, the vacuum port 114 can be both the inlet of the cleaning apparatus 100 when cleaning and vacuuming, and the outlet of the second airflow channel 402 when the base station 300 is vacuuming the trash objects in the cleaning apparatus 100.

Taking the number of air outlets 211 as two, for example, the dust inlet 212 and the two air outlets 211 are spaced apart and located on different sides of the dust box 20, where the two air outlets 211 are located on opposite sides of the dust box 20, and the dust inlet 212 is located in the middle of the two air outlets 211. In this embodiment, each air outlet 211 may be physically divided into multiple outlet areas, for example, each air outlet 211 may be divided into multiple outlet areas by intersecting rods longitudinally and horizontally. In FIG. 9 , an air outlet 211 is divided into two air outlet areas.

By setting two air outlets 211 located on the back sides of the dust box 20, the dust inlet 212 is located between the two air outlets 211, which can form two air ducts inside the dust box 20, so that the suction force is stronger and the airflow is more balanced, to ensure effective synergy between the two fans 141, and reduce the noise generated by the airflow.

The position of the air outlet 211 may correspond to the position of the exhaust port 116, and each air outlet 211 may correspond to at least one fan 141 (e.g., each outlet 211 is pumped by a different fan 141).

In some embodiments, the dust box 20 is formed with an access cavity 214 as shown in FIG. 9 and FIG. 10 . The access cavity 214 and the holding cavity 210 are spaced apart in the thickness direction of the dust box 20. For example, the dust box 20 has a substantially flat shape with a certain thickness. The holding cavity 210 and the access cavity 214 are provided at intervals in the thickness direction, for example, in a laminated setting. The airflow entering through the dust inlet 212 passes through the holding cavity 210 and then flows into the access cavity 214. The dust box 20 is formed with a connecting hole 215 that connects the holding cavity 210 and the access cavity 214. The air outlet 211 is connected to the access cavity 214. As the cleaning apparatus 100 sucks up the waste, the airflow enters from the holding cavity 210 through the connecting hole 215 into the access cavity 214, which in turn flows from the corresponding airflow path to the air outlet 211. As shown in FIG. 10 , the connecting hole 215 is provided with the filter 216 for filtering the air flow through the holding cavity 210 to the access cavity 214. As the cleaning apparatus 100 sucks up trash, the filter 216 filters the airflow from the holding cavity 210 through the connecting holes 215 into the access cavity 214, allowing the trash to remain in the holding cavity 210.

By providing the access cavity 214 connected to the air outlet 211, the space available for circulation in the dust box 20 is increased. Further, it facilitates the arrangement and arrangement of at least two air outlets 211, which in turn form at least two airflow paths with the cooperation of the air outlets 211 and the fan 141. Instead of directly extracting air from the holding cavity 210, the fan 141 does so through the access cavity 214, which facilitates waste deposition in the holding cavity 210 and further enhances the suction power and cleaning effect of the dust box 20.

The dust outlet 213 may be connected to the holding cavity 210 and not directly to the access cavity 214. For example, the dust outlet 213 is connected to the access cavity 214 via the holding cavity 210 and the connecting hole 215. When the base station 300 is vacuuming the trash objects in the dust box 20, a corresponding airflow channel is formed in the cleaning apparatus 100. For example, the second airflow channel 402, the exhaust port 116, and the dust inlet 212 may become the airflow inlet, where part of the airflow enters the holding cavity 210 through the exhaust port 116, the air outlet 211, the access cavity 214 and the connecting hole 215, and part of the airflow enters the holding cavity 210 through the vacuum port 114, the dust inlet 115, and the dust inlet 212. The airflow into the holding cavity 210 carries the waste objects in the holding cavity 210 from the dust outlet 213 to the dust collection box 311 of the base station 300 through the suction inlet 301.

If the filter 216 filters the airflow flowing into the access cavity 214 for a long time, it may have dust and other trash objects attached to it, and the airflow flowing from the holding cavity 210 to the access cavity 214 has difficulty in removing the trash objects from the filter 216. When the base station 300 is pumping the trash objects in the dust box 20, the airflow through the filter 216 flows from the access cavity 214 to the holding cavity 210 through the connecting hole 215, so that the reverse airflow can automatically clean the filter 216. The switching assembly 500 is used to intermittently seal at least one of the vacuum port 114, the exhaust port 116, the dust inlet 212, the air outlet 211 and/or the dust outlet 213.

Based on the above, the first embodiment can be further described as follows. As shown in FIG. 11 , the switching assembly 500 is provided at the base station 300 for intermittently blocking the second airflow channel 402. The switching assembly 500 may also be provided at the base 320 and opposite the vacuum port 114 (shown in FIG. 5 ) to enable intermittent blocking of the vacuum port 114.

As shown in FIGS. 12 and 13 , the base 320 has a mounting cavity 323, and the side of the base 320 for carrying the cleaning apparatus 100 is provided with a mounting hole 324 connected to the mounting cavity 323. For example, the second housing 322 is formed with a mounting cavity 323, and the mounting holes 324 are opened in a side wall of the second housing 322 for carrying the cleaning apparatus 100, and are connected to the mounting cavity 323. The mounting holes 324 and the vacuum port 114 of the cleaning apparatus 100 are set opposite each other when the cleaning apparatus 100 is carried on the base 320.

The drive member 510 and the blocking member 520 may be provided within the base 320, and the drive member 510 and the blocking member 520 are movably connected. The drive member 510 is used to drive the blocking member 520 to intermittently perform a telescoping action so that the blocking member 520 can intermittently extend out of the base 320 for blocking the vacuum port 114. The blocking member 520 and the driving member 510 may be provided in the mounting cavity 323. Further, the switching assembly 500 may comprise a first drive member 530 and a second drive member 540.

The first drive member 530 is movably disposed within the mounting cavity 323. The drive member 510 is connected to the first drive member 530. The first drive member 530 is connected to the blocking member 520. The drive member 510 is used to drive the first drive member 530 to move in the first direction, and the first drive member 530 can drive the blocking member 520 to extend out of the mounting hole 324 or retract into the mounting hole 324 in the second direction during the movement. In FIG. 12 , the blocking member 520 is retracted into the mounting hole 324, and in FIG. 13 , the blocking member 520 extends out of the mounting hole 324.

In this way, the blocking member 520 extends beyond the mounting hole 324 to block the vacuum port 114, which in turn intermittently blocks the second airflow channel 402, causing the pressure inside the holding cavity 210 and the access cavity 214 to change, thus allowing the waste objects attached to the dust box 20 to be loosened and effectively vacuumed. Moreover, since the blocking member 520 intermittently blocks the vacuum port 114 when the base station 300 is pumping the waste from the cleaning apparatus 100, part of the airflow in the dust box 20 can flow into the holding cavity 210 via the exhaust port 116, the access cavity 214, and the connecting hole 215, so that it can self-clean the filter 216 in the connecting hole 215, and the trash objects on the filter 216 may be loosened during the pressure change. In the process of pressure change, the garbage objects on the filter 216 may also be loosened, and then more easily fall into the holding cavity 210, and finally enter into the base station 300 with the airflow through the dust outlet 213, effectively improving the cleaning effect.

By setting the drive member 510 to drive the first drive member 530 to move in the first direction, and then drive the blocking member 520 to extend the mounting hole 324 or retract the mounting hole 324 in the second direction, the drive structure can effectively realize the intermittent movement of the blocking member 520 in the limited space of the mounting cavity 323, and the drive structure can also make the drive member 510 drive the blocking member. The drive structure also allows the drive member 510 to drive the blocking member 520 for smooth and reliable movement.

The drive member 510 is connected to the second drive member 540. The second drive member 540 is connected to the first drive member 530. The drive member 510 can drive the second drive member 540 to rotate, and the second drive member 540 moves the first drive member 530 in the first direction by rotation.

By setting the rotation of the second drive member 540 and the movement of the first drive member 530 in the first direction, the two different ways of movement can make the transmission structure more stable, and thus can guarantee the transmission efficiency of the drive member 510 and the blocking member 520.

As shown in FIG. 12 and FIG. 13 , the second drive member 540 can rotate around a predetermined axis. For example, the drive member 510 is used to drive the second drive member 540 to rotate around a predetermined axis, which in turn drives the first drive member 530 in the first direction. The drive member 510 has an output shaft, and the axis of the output shaft can be used as a preset axis. The second drive member 540 may be provided in a disc shape, and the axis of the second drive member 540 is the predetermined axis, and the axis of the drive member 510 may coincide or substantially coincide with the axis of the second drive member 540.

As shown in FIGS. 12-14 , the first drive member 530 is provided in a wedge shape. The first drive member 530 is provided opposite to the mounting hole 324. The first drive member 530 has a wedge-shaped surface 531 that is inclined with respect to the first direction and forms a height drop in the second direction. For example, there is a certain angle between the wedge-shaped surface 531 and the first direction, which is inclined, while the wedge-shaped surface 531 forms a height difference in the second direction, similar to a “slope” with a certain slope. The wedge-shaped surface 531 is oriented toward the mounting hole 324 and is provided opposite the mounting hole 324. The first drive member 530 slides in the first direction with its back to the wedge-shaped surface 531. The drive member 510 may comprise a motor.

The blocking member 520 abuts the wedge-shaped surface 531. During the rotation of the second drive member 540 driven by the drive member 510, the second drive member 540 drives the first drive member 530 to move in the first direction, and the movement of the wedge-shaped surface 531 causes the contact position between the blocking member 520 and the wedge-shaped surface 531 to change in height in the second direction, thus causing the blocking member 520 to extend out of the mounting hole 324 or retract into the mounting hole 324. The first drive member 530 is provided with a weight reduction slot 532, which may be opened from the wedge-shaped surface 531 so that the wedge-shaped surface 531 is a discontinuous face. The number of weight reduction slots 532 can be one or more. In other examples, the wedge-shaped surface 531 may also be a continuous and complete face.

The second drive member 540 is provided with an eccentric projection 541 that is offset from the predetermined axis. In an example, “eccentric” for the eccentric projection 541 may indicate that its axis is parallel or approximately parallel but not coincident with the preset axis. The axis of the eccentric projection 541 is offset from the axis of the second drive member 540, which is provided in a disc shape. The first drive member 530 is provided with a slide groove 533 spaced from the wedge-shaped surface 531. The eccentric projection 541 is slidable in the slide 533. As the drive member 510 drives the second drive member 540 to rotate, the eccentric projection 541 is able to rotate around a predetermined axis to slide in the slide groove 533, which in turn drives the first drive member 530 in the first direction.

By setting the slide groove 533 and eccentric projection 541, it can make the first transmission member 530 and the second transmission member 540 connected with high reliability, reduce the probability of the first transmission member 530 and the second transmission member 540 detaching from each other, and thus improve the reliability of the whole transmission structure. Since the rotating method is more stable in terms of travel and structure, the first drive member 530 is driven to move in the first direction using rotating movement, making the two movement methods work better with the transmission. The first direction and the second direction are perpendicular to each other. The extension direction of the slide groove 533 can be perpendicular to both the first direction and the second direction. The first direction may be the same or substantially the same as the direction in which the cleaning apparatus 100 is docked on the base 320.

In some embodiments, the output shaft of the drive member 510 is provided coaxially with the predetermined axis and is connected to the second drive member 540, which in turn drives the second drive member 540 to rotate around the predetermined axis. In other embodiments, the output shaft of the drive member 510 may be driven perpendicular to a predetermined axis, by the mutual engagement of two bevel gears (as shown in FIGS. 12 and 13 ), which in turn drive the second drive member 540.

The second drive member 540 can be set in a rod shape in addition to a disc setting, and can be other shapes. For example, one end of the rod or other shaped second drive member 540 is connected to the drive member 510, and the other end of the second drive member 540 is provided with an eccentric projection 541 such that the eccentric projection 541 can rotate around the axis of the output shaft of the drive member 510. Alternatively, the second drive member 540 may be a cam mechanism that uses the characteristics of the cam mechanism to move the first drive member 530 in the first direction.

As shown in FIGS. 12, 13, and 15 , the blocking member 520 may be restricted to move in the second direction, e.g., the blocking member 520 may be allowed to move in the second direction and not in the other direction. In this way, the reliability of the movement of the blocking member 520 can be improved and thus the cleaning apparatus 100 can be effectively blocked. The base 320 is provided with a first limiting portion 325 around the edge of the mounting hole 324. For example, the first limiting portion 325 encloses at least a portion of the edge of the mounting hole 324, and further may enclose all of the edge of the mounting hole 324. The first limiting portion 325 may extend in the second direction toward the mounting cavity 323, or project in the second direction toward the mounting cavity 323. For example, the space enclosed by the first limiting portion 325 is connected to the mounting hole 324, and the blocking member 520 can move within the space of the first limiting portion 325 and the mounting hole 324, and the first limiting portion 325 is used to regulate the path and direction of movement of the blocking member 520.

The shape of the first limiting portion 325 may match the shape of the blocking member 520, and the blocking member 520 is accommodated within the first limiting portion 325 to be restricted from moving in the second direction. For example, the blocking member 520 is accommodated within the space defined by the first limiting portion 325, which is connected to the mounting hole 324. In this way, the blocking member 520 can be made to move more snugly within the first limiting portion 325 and the mounting hole 324, reducing the looseness of the blocking member 520 and reducing the offset of the blocking member 520 moving in the second direction. Further, the blocking member 520, when retracted into the mounting hole 324, may also remain within the first limiting portion 325, thereby allowing the blocking member 520 to be more effectively and stably confined to move in the second direction.

The base 320 may be provided with a second limiting portion 326 in the mounting cavity 323. The second limiting portion 326 is used to limit the first drive member 530 so that the first drive member 530 is limited to moving in the first direction. As shown in FIG. 15 , the second limiting portion 326 may be provided on a side wall of the second housing 322 with mounting holes 324. For example, the second limiting portion 326 may include at least two side plates, two of which being provided opposite each other and fixed to a side wall of the base 320, the length direction of the two side plates being the same as the first direction. The first drive member 530 is able to slide between the two side plates, and since the two side plates have the same length direction as the first direction, this in turn allows the first drive member 530 to be restricted to move in the first direction. The width between the two side plates may be equal to or slightly greater than the width of the first drive member 530 so that the first drive member 530 can fit between the two side plates and the side walls of the first drive member 530 can be adjacent to the two side plates.

The first drive member 530 may be restricted to move in the first direction by the second limiting portion 326, which makes the movement of the first drive member 530 more stable, and can drive the blocking member 520 more stably and effectively, reducing the blocking action of the blocking member 520 from being performed incorrectly due to the unstable movement of the first drive member 530. The first limiting portion 325 may restrict the blocking member 520 to move in the second direction, which can further make the movement of the blocking member 520 more stable and enhance the stability of the whole structure.

As shown in FIGS. 12, 13 and 15 , the base 320 may be provided with a third limiting portion 327 within the mounting cavity 323. The third limiting portion 327 is used to limit the range of movement of the eccentric projection 541, and the third limiting portion 327 is provided, for example, in the form of an arc-shaped slot. For example, the shape of the third limiting portion 327 may be the trajectory of the rotation of the eccentric projection 541 around the predetermined axis, and is also used to limit the travel of the eccentric projection 541. The base 320 can also be provided with a fixed column 328 coaxially set with the preset axis, the second drive member 540 set in the fixed column 328, so that the fixed column 328 and the second drive member 540 are coaxially set with the preset axis. The second drive member 540 is capable of rotating around the axis of the fixed column 328. In this way, the eccentric projection 541 can rotate around the axis of the fixed column 328 at the third limiting portion 327, and the third limiting portion 327 can also make the structure more stable by reducing or avoiding the transmission failure of the eccentric projection 541, which may drive the first transmission member 530 due to disengagement.

As the first drive member 530 moves in the first direction, the drive blocking member 520 may move in the second direction. In this process, relative movement can be generated between the first drive member 530 and the blocking member 520, allowing the blocking member 520 to move in a second direction due to the height difference of the wedge-shaped surface 531. In order to make the relative motion between the first drive member 530 and the blocking member 520 more stable, the following structure can be further provided.

As shown in FIGS. 12 to 14 , the blocking member 520 is provided with a finite projection 521 on the side facing the first drive member 530. For example, the blocking member 520 is provided with the finite projection 521 on the side facing the wedge-shaped surface 531. Accordingly, the wedge-shaped surface 531 may be provided with an elongated restriction hole 534. For example, the wedge-shaped surface 531 is provided with the elongated restriction hole 534 in its inclined direction. The finite projection 521 is movably embedded in the elongated restriction hole 534. As the first drive member 530 moves in the first direction, the finite projection 521 may move within the limit hole 534 due to the relative movement between the blocking member 520 and the first drive member 530. The elongated restriction hole 534 can limit the finite projection 521 to limit the trajectory of the relative motion between the blocking member 520 and the first drive member 530, and then regulate the trajectory of the relative motion between the blocking member 520 and the first drive member 530, so that the relative motion between the blocking member 520 and the first drive member 530 is more stable and the transmission fit between them is more reliable.

In addition to the exemplary structures listed above, the switching assembly 500 of the first embodiment may be other structures and may enable intermittent blocking of the second airflow channel 402.

Based on the foregoing, the second embodiment may be further described below. The switching assembly 500 is provided at the base station 300 for intermittently blocking the first airflow channel 401. The switching assembly 500 may intermittently seal at least one of the suction inlet 301 and the suction outlet 302. The switching assembly 500 may also have a variety of structural forms, two of which are exemplarily illustrated below.

A first exemplary structure: The drive member 510 and the blocking member 520 are movably connected as shown in FIG. 16 . The drive member 510 is used to drive the blocking member 520 to intermittently perform a telescoping action to allow the blocking member 520 to intermittently extend to the suction inlet 301 or suction outlet 302, thereby intermittently blocking the first airflow channel 401.

The drive member 510 is fixedly provided inside the base station 300 and is provided adjacent to the suction inlet 301 or suction outlet 302. For example, the drive member 510 is provided on the side wall of base station 300 with the suction inlet 301 or the suction outlet 302, and drive member 510 drives the blocking member 520 to intermittently extend to suction inlet 301 or suction outlet 302. The blocking member 520 can block the suction inlet 301 or the suction outlet 302 when it extends to (e.g., covers) the suction inlet 301 or the suction outlet 302, and can leave the suction inlet 301 or the suction outlet 302 open after the retracting movement, thus enabling intermittent blocking of the first airflow channel 401. For example, the drive member 510 is movably connected to the blocking member 520 by a drive member, which is a retractable member, such as a telescopic rod, etc. The drive member 510 may comprise an electric motor, and the blocking member 520 can be provided in the form of a plate. In order to complete the movement, the corresponding parts, such as gears, slides and sliders, chains, belts, etc. may be matched, which can be set according to the actual situation, so as to allow the drive member 510 to drive the blocking member 520 in the corresponding direction to move back and forth intermittently, and then realize the “expansion” effect. The telescopic movement may include elastic telescopic movement as well as rigid back and forth movement. The telescoping effect created by the rigid back and forth movement extends into the suction inlet 301 or the suction outlet 302 and retracts out of the suction inlet 301 or the suction outlet 302. A corresponding track may also be provided within the base station 300 for intermittent back and forth movement of the blocking member 520 to achieve telescoping motion.

A second exemplary structure: The blocking member 520 is provided in a stretchable shape as shown in FIG. 17 . The diastolic shape may indicate that the blocking member 520 can achieve diastolic and contraction movements so that its area/volume can change, from large to small or from small to large. The blocking member 520 can move diaphragmically or contractionally, for example, to open or close like an “umbrella” or to expand or contract like a “balloon.”

The blocking member 520 can be set in the first airflow channel 401, set at the suction inlet 301 or the suction outlet 302. The driver member 510 may also be provided in the first airflow channel 401 or may also be provided at other locations in the base station 300. The drive member 510 is used to drive blocking member 520 to intermittently stretch or contract to enable intermittent blocking of first airflow channel 401.

The blocking member 520 may have a larger size (e.g., area, volume) when it is in a diastolic state, which in turn can block the first airflow channel 401, such as the suction inlet 301 or the suction outlet 302. When the blocking member 520 is in a contracted state, its size may be smaller, thus enabling the first airflow channel 401 to be open compared to the diaphragm state, so that the blocking member 520 is intermittently diaphragm and contraction, enabling intermittent blocking of the first airflow channel 401. In addition to the two exemplary structures listed above, the second embodiment may likewise adopt the structure of the switching assembly 500 described in the first embodiment, or may also be other structures.

Based on the foregoing, the third embodiment is further described below. In the third embodiment, the switching assembly 500 is provided in the cleaning apparatus 100 for intermittently blocking the second airflow channel 402. The switching assembly 500 can be provided in the main body 10 and/or the dust box 20.

For example, the switching assembly 500 may be provided in the dust box 20 for intermittently sealing the dust box passageway such that the pressure in the dust box passageway changes intermittently as the waste objects in the dust box 20 are being vacuumed. The switching assembly 500 can specifically intermittently seal the dust outlet 213, the dust inlet 212, or the air outlet 211, or it can also seal the connecting hole 215, the holding cavity 210, and/or inside the access cavity 214.

FIG. 18 illustrates an exemplary structure of a portion of the cross-sectional structure of the dust box along the A-A section line with the switching assembly 500. As shown in FIG. 18 , the drive member 510 and the blocking member 520 can be provided in the holding cavity 210, and the blocking member 520 is driven to make a telescoping motion to intermittently block the dust outlet 213 to achieve intermittent blocking of the dust box passage, i.e., the second airflow channel 402 can be intermittently blocked.

FIG. 19 illustrates another exemplary mating structure of a portion of the cross-sectional structure of the dust box with the switching assembly 500. As shown in FIG. 19 , the drive member 510 can be provided inside the holding cavity 210 or outside the holding cavity 210. The blocking member 520 may be provided in the second airflow channel 402, such as in the holding cavity 210 or in the dust outlet 213. The drive member 510 is used to drive the blocking member 520 to intermittently stretch or contract to be able to intermittently block the dust box passage, e.g., to intermittently block the second airflow channel 402.

For example, the switching assembly 500 may be provided in the main body 10 for intermittently blocking the body passage of the main body 10 such that the pressure in the body passage changes intermittently as the trash objects in the dust box 20 are being vacuumed. The main assembly 500 can specifically intermittently block the vacuum port 114, the connection port 115, and/or the exhaust port 116, etc.

In the third embodiment, the structure of the switching assembly 500 may be the same as the structure of the switching assembly 500 described in the first embodiment or the second embodiment. The third implementation uses the switching assembly 500 from the first implementation or the second implementation, and those skilled in the art are able to make some adaptations so that the switching assembly 500 from the first implementation or the second implementation can be applied in the third implementation.

As can be seen above, there are many forms of intermittent motion. For example, the drive member 510 can drive the blocking member 520 in a telescoping motion, which in turn extends into the suction channel 400, or retracts outside the suction channel 400, to achieve intermittent blocking of the suction channel 400. As another example, the drive member 510 can drive the blocking member 520 in a stretching motion, which in turn can stretch open within the suction channel 400 to block the suction channel 400, or contract within the suction channel 400 to allow the suction channel 400 to be unobstructed, enabling intermittent blocking of the suction channel 400. The drive member 510 can drive the blocking member 520 in a rotational or translational motion, so that the blocking member 520 can intermittently block the suction channel 400 by switching position through rotation or translation and intermittently located in the suction channel 400.

The base station 300 can achieve intermittent suction or similar pulse suction when suctioning the garbage objects in the cleaning apparatus 100, so that the suction process can produce pressure changes, so that the garbage objects attached to the cleaning apparatus 100 can be loosened, which makes the suction effect better, and also can clean the relevant parts of the cleaning apparatus 100, such as the filter 216, etc. The cleaning of the parts of the cleaning apparatus 100, such as the filter 216, is also possible.

The number of switching assemblies 500 can be multiple and can be provided at each of the above-mentioned ports on the base station 300 and the cleaning apparatus 100 that form the airflow channel, which will not be expanded in detail here. Each switching assembly 500 can perform the blocking action simultaneously or alternately.

Based on the foregoing description, exemplary function two of the present application cleaning system embodiment can be further described below. As shown in FIG. 20 , the base station 300 described in the base station embodiment of the present application may include a cleaning assembly 330, which may be provided, for example, in the base 320. The cleaning assembly 330 is used to clean the mopping mechanism of the cleaning apparatus 100 and is further described below.

As shown in FIG. 20 and FIG. 21 , the cleaning assembly 330 may comprise a guide tube 331 and the injection tube 332. The guide tube 331 is used to deliver the cleaning fluid to the injection tube 332. The injection tube 332 is used to spray cleaning fluid to the mopping member 134 of the cleaning apparatus 100. The guide tube 331 can be connected to the clear water tank 312 provided in the base station body 310, and the clear water tank 312 can supply the cleaning fluid to the guide tube 331.

The guide tube 331 is provided at the base 320. The base 320 is used to carry the cleaning apparatus 100, which in turn may allow the cleaning apparatus 100 to be set opposite the mopping member 134. The guide tube 331 and the injection tube 332 can be set in the cleaning slot 321, and the first pipeline t 1 of the clear water tank 312 can be extended to the cleaning slot 321 connected to the guide tube 331. The injection tube 332 can spray cleaning fluid outside the cleaning slot 321, which in turn can clean the cleaning apparatus 100. The sewage generated after cleaning can flow into the cleaning slot 321, which in turn can flow through the pipeline of the sewage tank 313 to the sewage tank 313. The injection tube 332 may project at least partially outside of the cleaning slot 321, which in turn allows for better cleaning of the cleaning apparatus 100.

The connection structure of the injection tube 332 and the guide tube 331 can take many forms, several of which are exemplified below. The first structural form: as shown in FIG. 22 , the injection tube 332 is rotatably connected to the guide tube 331. That is, the injection tube 332 can be rotated or pivoted with respect to the guide tube 331. The injection tube 332 is capable of rotating relative to the guide tube 331 and the base 320 and spraying water toward the mopping member 134 of the cleaning apparatus 100 to clean the mopping member 134 of the cleaning apparatus 100.

The spraying range formed by the rotation of the injection tube 332 may be circular or roughly circular, accordingly, the mopping member 134 can also be roughly circular set, the spraying range of the injection tube 332 can be greater than or equal to the area of the mopping member 134, so that it can better clean the mopping member 134.

By setting the injection tube 332 to be rotated relative to the guide tube 331, the injection tube 332 can achieve rotational spraying, which increases the spraying area. Unlike the turntable type spraying (e.g., carousel jetting), the present application may use the injection tube 332 to rotate and spray. This may save water and may achieve a similar or better result with a device of a smaller volume and weight. In addition, because the guide tube 331 is relatively fixed, it can improve the stability and fluidity of the water supply, so that the spraying process of the injection tube 332 can be performed more smoothly, and can improve the efficiency of spraying cleaning. The injection tube 332 and the guide tube 331 are cross-connected, and the injection tube 332 is rotated relative to the guide tube 331 using the connection position as the center of rotation. The extension direction of the injection tube 332 may be in the direction of its length, and the connection position of the injection tube 332 to the guide tube 331 is located between the ends of the injection tube 332 so that the maximum rotation radius of the injection tube 332 is greater than or equal to half the length of the injection tube 332. The injection tube 332 can be set in an “L” or arc shape, and the connection position with the guide tube 331 can be located between the two ends, or, the injection tube 332 can be set in an “X” shape, and the connection position with the guide tube 331 can be located at its intersection. In this way, the injection tube 332 has a wider spraying range, which in turn can better cover the mopping member 134 and improve the cleaning effect of the mopping member 134.

The injection tube 332 can be set in a flat shape. The axis of rotation of the injection tube 332 is perpendicular to its extension direction and in the same direction as its thickness. In this way, the injection tube 332 is flat set to make the connection between the guide tube 331 and the injection tube 332 more stable, which in turn makes the rotation of the injection tube 332 more smooth.

The guide tube 331 can also be set in a flat shape. The location of the connection between the guide tube 331 and the injection tube 332 may also be located between the two ends of the guide tube 331. The extension direction of the guide tube 331 may also be in the direction of its length. Alternatively, the guide tube 331 can be set in an “L” or arc shape, or the injection tube 332 can be set in an “X” shape. The axis of rotation of the injection tube 332 may be perpendicular to the thickness direction of the guide tube 331.

As shown in FIG. 22 , in order to make the rotational connection structure of both the injection tube 332 and the guide tube 331 more stable, the guide tube 331 may include two first tube sections 3311 and a first disc tube section 3312. The two first tube sections 3311 are each fixedly connected to the first disc tube section 3312, and each extends radially outward along the first disc tube section 3312. The two first tube sections 3311 may extend in the same direction and are set back-to-back on either side of the first disc tube section 3312. The number of first tube sections 3311 of the guide tube 331 may be greater than two, each provided in the first disc tube section 3312. By setting the number, extension direction and connection position of the first tube sections 3311, the guide tube 331 can be set in various shapes, such as “L” shape, “X” shape, etc.

The injection tube 332 may include two second tube sections 3321 and a second disc tube section 3322. Each of the two second tube sections 3321 may be fixedly connected to the second disc tube section 3322 and each may extend radially outward along the second disc tube section 3322. The two second pipe sections 3321 may extend in the same direction and are set back-to-back on either side of the second disc pipe section 3322. The number of second tube sections 3321 of the guide tube 331 may be greater than two, with each provided in a second disc tube section 3322. By setting the number of second pipe sections 3321, the extension direction and the connection position, the injection tube 332 can be set in various shapes, such as “L” shape, “X” shape, etc.

The first disc pipe section 3312 and the second disc pipe section 3322 may be coaxially provided and rotatingly connected. The injection pipe 332 and the connecting tube may be connected and connected through the first disc section 3312 and the second disc section 3322, which makes the support of the guide tube 331 to the injection tube 332 more stable and thus makes the rotatable connection between them more stable, and the larger area of the disc section is conducive to the setting of the connecting structure between them, which improves the reliability of the structure. The motor may be provided on the side of the guide tube 331 away from the injection tube 332, and its output shaft may extend into the first disc tube section 3312, which in turn connects to the second disc tube section 3322 to drive the second disc tube section 3322 to rotate. Alternatively, the motor may be provided within the first disc tube section 3312 of the guide tube 331.

As shown in FIG. 23 , the guide tube 331 may be provided with a first delivery channel 3310 extending in the direction of its extension. The guide tube 331 may be formed with an inlet hole 3313 connected to the first delivery channel 3310. The inlet hole 3313 may be provided in at least one of the first tube sections 3311, such as at one end of one of the first tube sections 3311. The liquid supply mechanism 316 can be connected to the inlet hole 3313 through the first pipeline t 1, which in turn allows the inlet hole 3313 to be connected to the clear water tank 312.

The injection tube 332 may be provided with a second delivery channel 3320 extending in the direction of its extension. The first delivery channel 3310 is connected to the second delivery channel 3320. The injection tube 332 is provided with a spray hole 3323 connected to the second delivery channel 3320 on the side of the injection tube 332 back from the guide tube 331. The spray holes 3323 are used to spray cleaning fluid to the mopping member 134 of the cleaning apparatus 100. The number of spray holes 3323 may be more than one, and a plurality of spray holes 3323 may be spaced along the extension direction of the injection pipe 332. Both second pipe sections 3321 and/or the second disc pipe sections 3322 may be provided with spray holes 3323. A plurality of spray holes 3323 can form a water curtain while spraying, effectively enhancing the spraying range and spraying efficiency in the process of rotating the spray.

The cleaning assembly 330 can also rub against the mopping member 134 when spraying cleaning solution to the mopping member 134 for cleaning, which in turn can improve the cleaning effect. The cleaning assembly 330 may comprise a scraping member 333. The scraping member 333 is used to rotate with the injection pipe 332 and rub the mopping member 134 with the spray cleaning fluid during the process of rotation to clean the mopping member 134 effectively .

The scraping member 333 can be set on the side of the injection tube 332 back from the guide tube 331 for contacting and scraping the mopping member 134 of the cleaning apparatus 100, and thus be able to scrape the mopping member 134 of the cleaning apparatus 100 while spraying cleaning fluid through the injection tube 332 to the mopping member 134 of the cleaning apparatus 100. The scraping member 333 may be at least partially exposed outside of the cleaning slot 321, and thus have better access to the mopping member 134.

The rotation of the injection pipe 332 while driving the scraping member 333 to scrape the mopping member 134 can realize the spraying and washing synchronization, which can effectively improve the cleaning effect.

The scratch member 333 may be spaced from the spray holes 3323. The scraping member 333 may also be provided at the outer periphery of the spray hole 3323. For example, the scraping member 333 may be provided in the form of a ring and is annularly disposed around the periphery of the spray hole 3323. By setting the scraping member 333 ring in the outer circumference of the spray hole 3323, it can make the scraping member 333 in the spray hole 3323 spraying the impact of a stronger position to rub against the mopping member 134, which in turn can further enhance the cleaning effect.

The number of scraper members 333 may be the same as the number of spray holes 3323. The number of spray holes 3323 may be more than one, and the number of scraping members 333 may be the same. Each spray hole 3323 may be provided with a circle of a respective scraping member 333 around the outer circumference. If the scraping member 333 is not provided in a ring, a ring of scraping member 333 may comprise a plurality of scraping members 333. If the scraping member 333 is set in a ring, a ring of scraping members 333 may be one scraping member 333 or a plurality of scraping members 333. The plurality of scrapers 333 and the plurality of spray holes 3323 may be staggered.

The scraping member 333 may be an elastic scraping member 333. For example, the material of the scraping member 333 can comprise rubber, silicone, and other soft elastic materials. Alternatively, the scraping member 333 may be a brush scraping member, which may comprise, for example, bristles fixed to the injection pipe 332.

The guide tube 331 may be provided with an air inlet hole 3314. The air inlet hole 3314 may be spaced from the inlet hole 3313. The air inlet hole 3314 may be located at the end of the first tube section 3311 (e.g., at an end of this first tube section 3311 away from the first disc tube section 3312). The air inlet hole 3314 may be connected to the first delivery channel 3310, and the air inlet hole 3314 is used to guide the dry gas to the first delivery channel 3310. The air supply mechanism 317 can be connected to the air inlet hole 3314 through the second line t 2. The spray hole 3323 is used to inject dry gas into the mopping member 134 of the cleaning apparatus 100.

In order to realize the alternate output of the liquid supply mechanism 316 and the gas supply mechanism 317, in addition to the aforementioned switching mechanism 319, it can be realized in the following way: the liquid supply mechanism 316 and the gas supply mechanism 317 can be switched to work through the corresponding control circuit of the base station 300. For example, when the cleaning work is carried out, the liquid supply mechanism 316 may work and the air supply mechanism 317 may not work, which in turn enables the cleaning work to be carried out through the guide tube 331 and the injection tube 332. When the drying work is done after cleaning, the air supply mechanism 317 may work and the liquid supply mechanism 316 may not work. Through the guide tube 331 set, the air inlet hole 3314 is connected to the first transport channel 3310, and then through the guide tube 331 and the injection pipe 332 to achieve rotary water spray cleaning and jet drying, can greatly improve the cleaning efficiency, simple structure and stable and reliable.

The second structure form and the first structure form are largely the same, the main difference is: the first structure form is to rotate to achieve rotational spraying, while the second structure form is to move back and forth along the preset direction to achieve spraying and cleaning. The differences between the second structural form and the first structural form are described below, and the similarities are referred to the descriptions in the first structural form.

For the second form of construction, as shown in FIG. 24 , the cleaning assembly 330 is provided in the base 320. At least a portion of the cleaning assembly 330 is capable of moving back and forth in a predetermined direction relative to the base 320 and is used to contact the mopping member 134 of the cleaning apparatus 100 and is capable of spraying cleaning fluid onto the mopping member 134 of the cleaning apparatus 100, thereby enabling cleaning of the mopping member 134 of the cleaning apparatus 100.

At least part of the cleaning assembly 330 can move back and forth in a predetermined direction relative to the base 320, so that a corresponding cleaning range can be formed in the predetermined direction. Accordingly, the mopping member 134 can be shaped accordingly. Setting at least part of the cleaning assembly 330 to move back and forth along the preset direction may facilitate the formation of a larger cleaning range, which can meet the non-regular shape of the cleaning of the mopping member 134. For example, the edge of the mopping member 134 may not be regular, if the cleaning range formed by the rotation method does not meet the cleaning requirements of the mopping member 134, the cleaning range formed by moving back and forth along the preset direction may extend to the farthest edge of the mopping member 134 position, which can meet the cleaning of the mopping member 134, so that it can adapt to the special-shaped mopping member 134. Moreover, by moving at least part of the cleaning assembly 330 back and forth in a predetermined direction, it is possible to spray and rub the mopping member 134 back and forth in the predetermined direction, which can greatly improve the cleaning efficiency.

At least the injection tube 332 is capable of moving back and forth in a predetermined direction relative to the base 320 and spraying cleaning fluid to the mopping member 134 of the cleaning apparatus 100. In this way, through the interplay of the injection tube 332 and the guide tube 331, the guide tube 331 may be used to guide the cleaning fluid to the injection tube 332. At least the injection tube 332 can move back and forth along the predetermined direction, to improve structural stability, and can move back and forth to form a more stable cleaning range through the injection tube 332. Further, the preset direction and the extension direction of the injection tube 332 does not overlap or cross set, so that the injection tube 332 can move back and forth to form a larger cleaning range. The extension direction of the injection tube 332 can be the direction of its length, and the preset direction can be perpendicular to the extension direction of the injection tube 332. A rectangular cleaning range can be formed with the distance moved back and forth as well as the length of the injection tube 332 on both sides, which in turn can better meet the shaped mopping member 134, such as semi-circular, oval or other shapes. The injection tube 332 may move back and forth in a predetermined direction relative to the guide tube 331 and the base 320, or the injection tube 332 and the guide tube 331 may move back and forth together in a predetermined direction relative to the base 320.

The guide tube 331 may be fixedly provided to the base 320. The injection tube 332 may be movably connected to the injection tube 332. The injection tube 332 is capable of moving back and forth in a predetermined direction relative to the guide tube 331, and in turn is capable of moving back and forth in a predetermined direction relative to the guide tube 331 and the base 320. The guide tube 331 and the injection tube 332 may remain connected as the injection tube 332 moves relative to the guide tube 331. The size of the cleaning slot 321 of the base 320 can be set to allow the injection tube 332 to move back and forth in a predetermined direction. For example, the injection tube 332 and the guide tube 331 can be roughly “cross” connected, and can also have other shapes or connection structure.

As shown in FIG. 24 and FIG. 25 , the base 320 in the cleaning slot 321 can be provided with a first slide 329 extending along a predetermined direction, the injection tube 332 can be provided with a first slider 3324 matching the first slide 329, and the first slider 3324 can be movably set in the first slide 329. The injection tube 332 can move in a predetermined direction relative to the base 320 through the first slider 3324 and the first slide 329. The guide tube 331 can be fixed to the base 320, and in turn the injection tube332 can move relative to the guide tube 331.

Further, the injection tube 332 is movably connected to the guide tube 331, for example, the guide tube 331 may be provided with a second slide 3315 extending in a predetermined direction, and the injection tube 332 may be further provided with a second slider 3325 matching the second slide 3315, and the second slider 3325 is movably provided in the second slide 3315, and the injection tube 332 is moved relative to the base 320 and the guide tube 331 by the cooperation of the first slider 3324 and the first slide rail 329, and the second slider 3325 and the second slide rail 3315, moving in a predetermined direction relative to the base 320 and the guide tube 331.

For example, the number of first slides 329 can be two, corresponding to the two ends of the injection tube 332, and the injection tube 332 is provided with a corresponding first slider 3324 at each of its ends. The extension direction of the guide tube 331 can be the same as the preset direction, and the extension direction of the injection tube 332 can be perpendicular to the preset direction.

The guide tube 331 may be connected to the injection tube 332 through at least one hose. The length of the hose can match the sliding stroke of the injection tube 332 to allow the injection tube 332 to remain connected to the guide tube 331 during the sliding process.

In other embodiments, the guide tube 331 may be a hose, and/or a retractable rigid tube, as shown in FIG. 26 . Retractable rigid tubes are for example rigid retractable sleeves. The injection tube 332 is connected to the guide tube 331. As the injection tube 332 moves back and forth in a predetermined direction, the guide tube 331 may generate a telescoping motion to accommodate the back and forth movement of the injection tube 332. Similarly, the injection tube 332 can drag the guide tube 331, which produces a telescoping motion. The length of the guide tube 331 can meet the maximum travel distance of the injection tube 332. For example, one end of the guide tube 331 is connected to the corresponding pipeline of the clear water tank 312, such as the first pipeline t 1, and the other end or central position of the guide tube 331 can be connected to the injection tube 332, and the connection position of the guide tube 331 and the injection tube 332 can be relatively telescopic with respect to one end of the guide tube 331 during the movement of the injection tube 332. Further, the other end of the guide tube 331 can be connected to a corresponding pipeline of the air supply mechanism 317, such as the second pipeline t 2, and the injection tube 332 is connected between the two ends of the guide tube 331. The connection position of the guide tube 331 and the injection tube 332 can be telescoped relative to the two ends of the guide tube 331. In addition to the slider and slide mating structure, the movable connection between the injection tube 332 and the guide tube 331 can also use other common sliding structures.

For the injection pipe 332 and the guide tube 331 to move back and forth in a predetermined direction relative to the base 320, the injection tube 332 and the guide tube 331 are relatively fixed, such as fixedly connected, and can move back and forth in a predetermined direction relative to the base 320 together.

As shown in FIG. 27 , the base 320 may be provided with the first slide 329 extending along a predetermined direction within the cleaning slot 321. The injection tube 332 may be provided with the first slider 3324 accordingly. The first slider 3324 is movably provided on the first slide 329. The injection tube 332 is able to move in a predetermined direction relative to the base 320 through the cooperation of the first slider 3324 and the first slide rail 329. The injection tube 332 can drive the guide tube 331 as it moves. The guide tube 331 can also be provided with a third slider 3316, the base 320 in the cleaning slot 321 can be set correspondingly with the guide tube 331 of the third slider 3316 matching the third slide 3200, the guide tube 331 can be moved relative to the base 320 through the third slider 3316 and the third slide 3200. The guide tube 331 and the injection tube 332 can be connected (e.g., by a hose). The base 320 can be opened with a holding slot (not shown), and the guide tube 331 may be movable and embedded in the holding slot. The guide tube 331 in the holding slot when the slide can drive the injection tube 332 in a predetermined direction, or the injection tube 332 in a predetermined direction to move back and forth can drive the slide of the guide tube 331 in the holding slot. It can also be a movable connection between the guide tube 331 and the base 320 using sliders and slides, etc., to drive the injection tube 332 to move during the movement of the guide tube 331.

In addition to the slider and slide mating structure, the movable connection between the injection tube 332 and/or the guide tube 331 and the base 320 can also be made with other sliding mating structures. In the second structure form, the shape structure and connection relationship of the scraping member 333, the injection tube 332, and the guide tube 331 can be referred to the first structure form, and will not be repeated here.

In addition, for the two structural forms described above, the guide tube 331 may not be provided with an air inlet hole 3314. The cleaning assembly 330 may further include a gas guide tube (not shown) that connects to the injection tube 332, which in turn delivers the drying gas to the injection tube 332. The gas guide tube can be independent of the guide tube 331, corresponding to the delivery of cleaning fluid and drying gas to the injection tube 332.

As shown in FIG. 28 , the dust box 20 may comprise a dust box body 21 and an electrostatic assembly 22. The dust box body 21 can be opened with a dust inlet 212, a holding space 200 and an air outlet 211, with the dust inlet 212 and the air outlet 211 each connected to the holding space 200. The electrostatic assembly 22 is provided in the holding space 200. The electrostatic assembly 22 is located between the dust inlet 212 and the air outlet 211. For example, the electrostatic assembly 22 may space the holding space 200 apart, which in turn may allow the dust inlet 212 and the air outlet 211 to be connected to the portions of the holding space 200 located on either side of the electrostatic assembly 22, respectively.

The dust box 20 may comprise a first filter member 23 and a second filter member 24. The first filter member 23 may be provided at the dust inlet 212, or between the electrostatic assembly 22 and the dust inlet 212. In this way, the larger waste objects or particles carried by the airflow can be initially absorbed to facilitate further adsorption action of the subsequent electrostatic assembly 22 and improve the adsorption efficiency. The first filter member 23 is, for example, a HEPA filter. The second filter member 24 is provided at the air outlet 211, or between the electrostatic assembly 22 and the air outlet 211. By providing the second filtering member 24 between the air outlet 211 or the air outlet 211 and the electrostatic assembly 22, it can minimize the airflow carrying the missed dust or garbage objects out, so that the garbage objects can be better retained in the holding space 200. The second filter member 24 can be a sponge. The electrostatic assembly 22 may be provided between the first filter member 23 and the second filter member 24.

As shown in FIGS. 28 and 29 , the electrostatic assembly 22 may be provided with a through hole 220. The through hole 220 is used to direct the airflow in the holding space 200 from the side of the electrostatic assembly 22 near the dust inlet 212 to the side of the electrostatic assembly 22 near the air outlet 211. In an example, the side of the electrostatic assembly 22 near the dust inlet 212 may refer to the side structurally near the dust inlet 212, or it may refer to the side near the dust inlet 212 in the direction of air flow. Similarly, the side of the electrostatic assembly 22 near the air outlet 211 may refer to the side structurally near the air outlet 211, or it may refer to the side near the air outlet 211 in the direction of airflow. The electrostatic assembly 22 is used for adsorption deposition of dust carried by the airflow after flowing through the through hole 220 by its incidental electrostatic force.

After the air flow enters the holding space 200 through the dust inlet 212, it enters the side of the electrostatic assembly 22 near the dust inlet 212, then enters the side of the electrostatic assembly 22 near the air outlet 211 through the through hole 220 of the electrostatic assembly 22, and then exits through the air outlet 211.

When the cleaning apparatus 100 is working, the suction force is generated in the holding space 200 so that the waste enter the holding space 200 with the airflow, the airflow enters the holding space 200 and hits the electrostatic component 22, thus the speed decreases, which is conducive to the settling of the waste and dust. After entering from the side near the dust inlet 212 to the side near the air outlet 211, the buffering effect may be generated once again due to the small passage into the larger space, and the buffering area may be formed on both sides after passing through the through hole 220, so that the electrostatic component 22 can further absorb the smaller dust carried by the airflow after passing through the through hole 220 through its attached electrostatic force, which can absorb the dust more effectively and improve the efficiency of dust absorption, and then make the dust remain in the holding space 200. The cleaning efficiency of the cleaning apparatus 100 can ultimately be improved.

In addition, the second filter 24 is set between the air outlet 211 or the electrostatic assembly 22 and the air outlet 211, which can also optimize the airflow in the holding space 200, making the airflow more uniform, and then the buffering and deceleration effect of the airflow after flowing through the through hole 220 is more obvious, reducing the impact of the extreme speed of the air outlet 211 on the buffering effect, and can improve the efficiency of the electrostatic assembly 22.

For example, the number of through holes 220 may be one or more, and a plurality of through holes 220 may be spaced open in the electrostatic assembly 22. This allows the electrostatic assembly 22 to be set in a roughly net-like configuration. For example, two adjacent through holes 220 are spaced 1-5 mm apart.

As shown in FIG. 29 , the electrostatic assembly 22 may include a substrate 221 and an electrostatic attachment member 222. The substrate 221 is provided within the holding space 200 and may divide the holding space 200. The through holes 220 are provided in substrate 221. The electrostatic attachment member 222 is attached to the side of the substrate 221 near the air outlet 211. The electrostatic attachment member 222 is used to absorb and deposit the dust carried by the airflow after flowing through the through hole 220 by the electrostatic force attached to it. Providing substrate 221 to divide the holding space 200 can make the structure more reliable, can enable the electrostatic attachment member 222 to be connected to the substrate 221, and can enhance the efficiency of dust adsorption.

The base plate 221 is a metal substrate for electrical connection to the electrostatic generator 25. The electrostatic generator 25 can be set on the dust box body 21 or outside the dust box body 21. The electrostatic generator 25 can be connected to the corresponding power supply of the cleaning apparatus 100. The electrostatic generator 25 may be a component of the electrostatic assembly 22. The electrostatic generator 25 is used for the electric charge generated on the substrate 221, which is able to attach to the electrostatic attachment member 222. In this way, the charge attached to the electrostatic attachment member 222 can form a more stable adsorption effect. The electric charge is, for example, negative ions.

The electrostatic attachment member 222 may include a fleece member (not shown). The fleece member is provided on the side of the substrate 221 near the air outlet 211. For example, the side of the substrate 221 near the air outlet 211 can be implanted with a fleece member. The fluffy member is used to attach to the electrical charge generated on the substrate 221.

The base plate 221 is provided with an insulating layer 223 on the side near the dust inlet 212. An insulating layer 223 is provided on the side of the substrate 221 near the dust inlet 212 to allow better electrostatic adsorption of dust after passing through the through hole 220. And the provision of insulating layer 223 also enables the provision of two or more electrostatic components 22 in the holding space 200. The dust from the dust inlet 212 into the holding space 200 after the impact on the substrate 221 near the side of the dust inlet 212, the speed slowed down, after passing through the hole 220 again into the larger space to produce a buffer effect, which makes the dust can effectively be electrostatic adsorption, can make the smaller dust can also be absorbed, to improve the efficiency of dust adsorption.

The number of electrostatic components 22 may be at least two. The electrostatic assemblies 22 may be spaced apart in the holding space 200, and the through holes 220 of any adjacent electrostatic assemblies 22 are staggered. For example, the axes of the through holes 220 of any two adjacent electrostatic assemblies 22 do not overlap. By providing at least two electrostatic components 22, adjacent to the two electrostatic components 22 through hole 220 staggered set, the air may flow through the dust inlet 212 into the final outflow through the air outlet 211, which allows the dust to be absorbed several times to improve the adsorption efficiency, so that the final outflow of air is clean. This may improve the environmental protection efficiency and the cleaning effect.

In order to more effectively cushion the airflow after passing through the through holes 220, the substrate 221 can be formed with a raised portion 2211 on the side near the air outlet 211. The through holes 220 are provided in the projections 2211 to connect or run through the opposing sides of the substrate 221. For example, the projection 2211 may be raised on the side of the substrate 221 near the air outlet 211. Further, the projections 2211 may be raised on both sides of the substrate 221. The through holes 220 may run through the projections 2211, connecting the sides of the substrate 221. The through hole 220 may be a channel with a certain length. In this way, the through hole 220 may be considered a small tunnel area with respect to the portion of the space of the holding space 200 located near the exit side of the substrate 221, while that portion of the space of the holding space 200 may be considered a large tunnel area. In an example, the electrostatic attachment member 222 is provided on the side of the substrate 221 near the air outlet 211 and may include an outer periphery extending to the projection 2211.

The airflow through the through hole 220 of the projection 2211, then in the through hole 220 has a certain flow distance, faster speed, into the substrate 221 near the air outlet 211 side of the part of the space, into a larger space, the speed slowed down, which further produces a more effective buffer effect, and then the airflow may flow to both sides of the area of the through hole 220, so that the electrostatic The attachment member 222 can better absorb dust through electrostatic, to achieve good dust removal effect.

As shown in FIG. 29 , the diameter of the through hole 220 gradually decreases in the direction from the side of the substrate 221 near the dust inlet 212 to the side of the substrate 221 near the air outlet 211. For example, the diameter of the through hole 220 gradually decreases in the direction of the flow of air within the through hole 220. In this way, the velocity of the airflow in the through hole 220 can be gradually increased, and then make the airflow through the through hole 220 to a larger space to produce a more effective buffer effect, the airflow can drive the dust flow to the sides of the through hole 220, that is, at least part of the airflow back toward the electrostatic attachment member 222, and then can be absorbed by the electrostatic attachment member 222.

The area where the projection 2211 and the substrate 221 connect the projection 2211 has a rounded transition. In this way, the projection 2211 has the shape of a “hill” and can better absorb the slow-running dust.

As shown in FIG. 30 , the holding space 200 may include the holding cavity 210 and the access cavity 214, with the access cavity 214 and the holding cavity 210 connected by a connecting hole 215. The connecting hole 215 is located between the dust inlet 212 and the air outlet 211. That is, the dust box body 21 is opened with spaced out holding cavities 210 and access cavities 214, as shown in FIG. 9 and FIG. 10 . The holding cavity 210 and the access cavity 214 are connected through the connecting hole 215, which can form the holding space 200. FIG. 9 and FIG. 10 illustrate only an exemplary structure of the dust box body 21, and the positions regarding the dust inlet 212, the air outlet 211 and the connecting holes 215, as well as the holding cavity 210 and the access cavity 214, etc. can be adjusted as desired. The electrostatic assembly 22 may be provided in the access cavity 214, located between the air outlet 211 and the connecting hole 215, and also necessarily between the dust inlet 212 and the air outlet 211. The holding cavity 210 is used to hold trash objects, but there may still be some particulate dust into the access cavity 214, and the electrostatic components 22 can strengthen the adsorption of smaller particles of dust and other trash objects to enhance the cleaning effect, making the airflow from the air outlet 211 cleaner and more environmentally friendly.

The filter 216 is provided inside the connecting hole 215. Alternatively, the first filter member 23 is provided in the connecting hole 215, in other words, the filter 216 can act as the first filter member 23, so that most of the waste objects are intercepted in the holding cavity 210, and the electrostatic component 22 in the access cavity 214 can further absorb small particles of dust and other waste objects to enhance the cleaning efficiency through multiple filtration and adsorption.

The electrostatic assembly 22 may also be provided in the holding cavity 210, located between the dust inlet 212 and the connecting hole 215. Alternatively, both the holding cavity 210 and the access cavity 214 may be provided with electrostatic components 22.

This embodiment by opening a through hole 220 in the electrostatic component 22, so that the airflow in the flow through the through hole 220 into the holding space 200 is located in the electrostatic component 22 near the air outlet 211 part of the space to produce a buffer effect, slowing down the speed, the electrostatic component 22 can through its incidental electrostatic on the flow through the through hole 220 after the airflow of dust carried by adsorption, improve the efficiency of dust absorption and cleaning.
